Possible Cure for H.I.V.
Researchers are hoping they are one step closer to a HIV vaccine – using HIV. At the 6th International AIDS Society Conference on HIV Pathogens, Treatment, and Prevention in Rome, researchers with the Maryland-based VirxSys Corporation announced the findings of their VRX1273 vaccine. The vaccine is a genetically altered version of SIV, the version of HIV found in non-human primates. Over the course of six months, five infected monkeys were injected with the vaccine three times, while five others were given a placebo vaccine. After 18 months, it was found that 40% of the vaccinated monkeys had very low to undetectable amounts of virus in their bodies. “We are well on the path to a functional cure, at least in monkeys,” says Laurent Humeau, VirxSys vice president of research and development. “Although this pre-clinical study is modest in terms of size, it is highly unusual to see near non-detectable levels of the virus not only circulating in the blood, but also in the reservoi
